Hai,

very urgent.

Thanks in Advance



This is my code



protected void Page_Load(objec t sender, EventArgs e)
{

if (IsPostBack)
{

if (ViewState["ControlsCo unt"] != null)
{

reloadcontrols( );

}
}
}


In my buttonclick event:


protected void btnAdd_Click(ob ject sender, EventArgs e)
{

ViewState["ControlsCo unt"] = ViewState["ControlsCo unt"] == null ? 1 : (int)ViewState["ControlsCo unt"] + 1;
int ControlsCount = Convert.ToInt32 (ViewState["ControlsCo unt"]);
TextBox txtbox = new TextBox();
txtbox.ID = "TextBoxID" + ControlsCount.T oString();
txtbox.Width = 150;
Panel1.Controls .Add(txtbox);
Panel1.Controls .Add(new LiteralControl( ));
}



private void reloadcontrols( )
{
int ControlsCount = Convert.ToInt32 (ViewState["ControlsCo unt"]);
for (int i = 0; i < ControlsCount; i++)
{
DataTable dt = Add();
int Rowval = dt.Rows.Count;
objlog.Write("r owvalue" + Rowval.ToString ());
if (Rowval < 1)
{
Insertvalue();
}
else
{
int Rowcount = int.Parse(dt.Ro ws[0]["count"].ToString());
Rowcount1 = Rowcount + 1;
updatevalue(Row count1);
}


TextBox txtbox = new TextBox();
txtbox.ID = "TextBoxID" + Rowcount1;
txtbox.Width = 150;
Panel1.Controls .Add(txtbox);
Panel1.Controls .Add(new
LiteralControl( "&nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp"));

}
